"There are hundreds of thousands of hospitalizations, and tens of thousands of deaths in the United States every year because of the flu, most of which could be prevented with a flu shot", said guideline co-author Dr. John Kelso.
Clark County saw more than 40 flu-related hospitalizations during the last flu season, a majority of which involved people ages 60 and older, according to the Clark County Combined Health District.
A year ago flu activity didn't reach this level statewide until mid-January, according to the Ohio Department of Health.
"Well the flu can be deadly, previous year OH had 7 children die from the flu, the elderly are more susceptible to die".
However, not everyone in that range has been able to get the vaccine to date. "The overwhelming evidence since 2011 has shown that a flu shot poses no greater risk to those with egg allergy than those without".
Most flu vaccines administered today are manufactured using chicken eggs and contain trace amounts of a protein called ovalbumin.
Specifically, the health organizations all found that potential harms of the flu - which for some can be life-threatening - outweighed any potential risks, especially since there is no proven record of people with egg allergies having bad reactions to the flu shot.
"Egg allergy primarily affects young children, who are also particularly vulnerable to the flu", Kelso added.
Ask about egg allergy before giving the vaccine. No one in the studies had a severe reaction.
She said this year's flu shot is only 10 percent effective, but says it's better than going unprotected.
It's safe for people with an egg allergy to get a flu shot, says a leading US allergists' group. She said there are three main strains of flu going around.
"That doesn't rule out that somebody might react to the influenza vaccine", Greenhawt said.
The vaccine has been offered to eligible children in reception class and school Years 1 to 4 in primary school.
"This is the best preventative measure we have against contracting influenza", Greenhawt said.
